In his role as an investigator with the
CCCRP's portfolio for Photonics and
Light-Based Innovation for Severe Injury,
Botvinick's lactate monitor satis es the
Army's desire for smaller, better technolo-
gies to operate in combat scenarios that
will likely play out in denser, more urban
areas, and in which prolonged eld medi-
cal care will likely be the norm. Lactate is
the chemical form of lactic acid that the
body produces and uses.
" e vision [for the device] is something
like a blister pack that you would peel
open in the eld and then a medic would
just slap it on the body," says Botvinick.
"And in that simple act of slapping, an
insertion needle would be guided just
under the skin [...] and then by pull-
ing back on a sticker or tab, that needle
would be removed and just a exible ber
would remain."
at tiny ber would then interrogate the
tissue around it, asking how much lactate
exists in the area, according to Botvinick.
From there, the assembled information
would then be transmitted via Bluetooth
technology to a wearable unit on the skin.
While measuring lactate is not currently
the standard of care in the eld (chie y
because current protocol requires blood
samples to be drawn and then sent to a
lab for study, a logistical nightmare in
the eld), Botvinick's sensor measures
lactate faster than the lactate level within
the body can change, which makes it
ideal for the uidity of long-term trans-
port situations, as well as transportation
between levels of care. As such, a number
of prototype devices are being prepared
for shipment to the U.S. Army Institute
of Surgical Research in San Antonio for
animal model testing.
is is just one example from a research
program rich with potential solutions.

CHARTING EXERTION LEVELS
A readout of lactate levels over time as measured by a continuous lactate
monitor over a period of cycling. Lactic acid levels rise during episodes of
critical illness and internal bleeding, which may not be visible to the naked eye.
